I live in a beautiful seaside community that's got more dog poop on the ground than 'Animal Waste Ordinance' signs - and there seems to be one of those every 500 feet. Some of the neighbors have put up creative signs like this. It helps, a bit.

Others have that cut out of the white dog squatting with the dangling poop that says NO. I find the dangling thing redundant and have to supress the urge to pull that poop off.

Still, as nice as neighborhood as this is, ignorant is as ignorant does. Last person I asked nicely 'I have an extra bag if you need it' verbally assaulted me! Her dog was offlead too and I was ready to pepperspray the pair of them if they came anywhere near me and Otto.
